Hi,Your protoboard has a break in the red and blue side conductors in the middle, if you follow the red and blue lines they are not continuous all the way down the edge of the board.You will need to jumper them if you need continuity down the entire length.
I programmed two unused pins to provide power to the LM35 and relay, LM35 seems to work fine but the relay power seems to low even though it is working.
